ftdi_eeprom - Tool for reading/erasing/flashing FTDI USB chip eeproms

SYNOPSIS

ftdi_eeprom [commands] config-file

DESCRIPTION

ftdi_eeprom is a small tool for reading/erasing/flashing FTDI USB chip eeproms. It uses
libftdi to access the chip, so you will need to have the required permissions on the
device.

The ftdi_sio module should not be loaded. You can prevent it to be automatically loaded by
adding it to /etc/modprobe.d/blacklist.

You have to unplug and replug your device to get the new values to be read. Otherwise,
you will still get the old values.

COMMANDS

--read-eeprom
Read eeprom and write to ‐filename‐ from config-file.

--erase-eeprom
Erase eeprom.

--flash-eeprom
Flash eeprom.

CONFIGURATION FILE

The configuration file contains a list of key-value pairs which will be used to flash an
FTDI USB chip eeprom. Comments start with #. The beginning of such a file might look like
the following:

vendor_id=0x0403 # Vendor ID
product_id=0x6001 # Product ID

max_power=0 # Max. power consumption: value * 2 mA. Use 0 if self_powered = true.

###########
# Strings #
###########
manufacturer="ACME Inc" # Manufacturer
product="USB Serial Converter" # Product
serial="08-15" # Serial

The example configuration file that could be found in /usr/share/doc/ftdi-eeprom/examples
is quite well commented so you should be able to use it as a basis. The following keys
are supported:

vendor_id
Set the vendor ID of the device. This value could be entered in decimal or
hexadecimal form, and should be in the range 0-65535 or 0x0000-0xffff,
respectively.

product_id
Set the product ID of the device. This value could be entered in decimal or
hexadecimal form, and should be in the range 0-65535 or 0x0000-0xffff,
respectively.

max_power
Set the maximum current the device will use, in 2 mA unit. Use 0 if self_powered =
true.

manufacturer
Set the manufacturer string which normally holds the name of the manufacturer.

product
Set the product string which normally holds the name of the product.

serial Set the serial string which normally holds the serial number of the product.

self_powered
Specify if the device is self-powered or not. The value should be true or false.

remote_wakeup
Specify if the device supports remote wake-ups. The value should be true or false.

use_serial
If this value is set to true, the serial string will be used. Otherwise the default
serial string will be used.

BM_type_chip
This value have to be set to true if you are using a BM chip.

in_is_isochronous
If set to true this option specify that the input endpoint is in isochronous mode.

out_is_isochronous
If set to true this option specify that the output endpoint is in isochronous mode.

suspend_pull_downs
If this value is set to true the pull downs are enabled during suspend for lower
power consumption.

change_usb_version
This value has to be set to true if you want to force the USB version using the
usb_version key. Otherwise the default USB version will be used.

usb_version
Set the USB version of the device. The change_usb_version value has to be set to
true.

filename
Specify a filename if you want to dump the content of the eeprom into it.
